I think that is better (more explicit). We could even consider using
something other than main(), such as daborun() or something, so that
people can decide whether their code can run as a script, in daborun, or
both:
def main():
# Runs if we are run as a script.
def daborun():
# Runs if we are called from daborun.
# User code can do additional stuff, and conditionally choose to
# call the main() function - user code "knows" that it is being
# run from daborun. This may prove fruitful in the future for
# reasons unbeknownst to us now.
main()
if __name__=="__main__":
# We know we are the main script.
main()
I say this only because we are now in the position to name it, and in
the future we'll have to live with the decision. Many Python scripts
will have main() functions, so perhaps it would be better if we chose
something that pretty much guarantees the given script is a dabo script.
